ORAL MEDICATIONS Flashcards
medication
substance used in diagnosis, treatment cure, relief of prevent health alteration
medication may be prescription, non-prescription, complementary/herbal preparation
acute care - RN roles
ensure pt. prepared to administer meds when discharged
educate pt. about meds & side effects
ensure med regimes are ‘fit for purpose’, practice & sustainable
assesses effects of meds in restoring/maintaining health
Aus national med policy
maximise indiv. benefit from med regime
achieve safe, effective & appropriate use of meds & optimise medicinal use
quality use of medicines
aus response -> National Medicines Policy
wise -> ensuring best treatment plan
necessary -> ensuring when meds are needed, theyre carefully selected, managed, monitored & reviewed
safe & effective -> minimising misuse, overuse & underuse while achieving goals of therapy by delivering beneficial changes in health outcomes
medication team
prescriber
nurse
pharmacists
medication management cycle
working together in all aspects to prevent an error
prescriber -> prescribe/issue med
pharmacist -> review medicine order, issue of med, education patient
nurse -> distribute/storage of med, adminster/monitor med response, transfer of verified info, educate patient
RNs role in meds
RN’s prescribing/administering meds are accountable for knowing meds prescribed, therapeutic/non-therapeutic effects & patients need for med
provides education to patient & family about med & effects
assesess patients need for med before dose
evaluates therapeutic & non-therapeutic effects of medication & clinical outcomes
errors in medication cycle
ordering, transcribing, dispensing, administering
O-> wrong dose, drug, route/form, allergy/drug interaction
T -> dose, route, patient, time, drug
D -> dose, route, patient, time, incorrect labelling/drug ID, primary catch for allergy/drug interaction
A -> patient, dose, drug, time/omitted, route, frequently involves infusion pump
pharmacokinetics
study how medication enters body, moves through body & leaves body
pharmacodynamics
process in which med interacts with body cells to produce biological response
therapeutic effect
desired result or action of med
absorption
passage of a drug from administration site to bloodstream
distribution
process of delivering mediation to tissues, organs & the specific site of action
metabolism
process by which drug is altered to less active form to prepare for excretion
excretion
process removes less active drug or its metabolites
adverse drug reaction
harmful unintended reaction to medicines that occur at doses normally used for treatment
medication interactions
when drug action is modified by presence of certain food/herb or other medication
antagonism
occurs when drug effect is decreased by taking the drug with another substance
drug incompatibility
mixing medications in solution that causes precipitation or combining drug with another that causes adverse chemical reaction
diversity considerations
pregnancy -> extreme risk to developing foetus
infants -> require smaller doses
older adults -> increased side effects
gender -> drug actions differ based on hormone levels & distribution of body fat
genetics -> affecting drug metabolism & influence dosage needs
cultural factors -> herbal med may affect action of prescribed meds
pharmacodynamics
drugs half life -> expected time it takes for blood conc. to measure half of original drug dose due to drug elimination
onset of action -> time body takes to respond to drug after administration
plasma plasma level -> indicated highest serum (blood) concentration
trough -> lowest serum level of medication
side effects
predictable but unwanted & sometimes unavoidable reactions to medications
toxic effects
result from medication overdose or the buildup of medication in the blood due to impaired metabolism & excretion
allergic reactions
unpredictable immune responses to medications
routes of administration
Oral Routes -> oral, sublingual, buccal
Parenteral Routes -> subcutaneous, intradermal, intravenous, intramuscular, epidural, intrathecal, intraosseus, intraperitoneal, intradermal, intraarterial
Topical Routes -> skin, mucous membranes, inhalation, introcular
dosage calcs
Tablets -> dose required = amount to be administered stock strength
Liquids -> dose required x volume = amount administered stock strength
benefits of EMMS
fewer prescribing errors
lower dispensing errors through med orders, automation & barcode scanning
reduced admin errors through clearer info
less omission/commission errors in care through improved info transfer
improved med adherence & minimised misuse, overuse & underuse of meds
medication errors
any event that could cause/lead to incorrect administration to prescribers orders
may occur when RN fails to follow routine procedures
preventable errors
use of incorrect drug
prescribing errors
administration errors
incorrect drug
legal/valid orders
written/printed in ink / entered in EMMS
signed by prescriber & contact number
full name of recipient, medication, dosage, route, frequency
reason for administration
detail the number of times drug may be dispensed or time between repeated administrations
reason for med
RN must assess if reason for med is valid
medicine needs to be assessed as being appropriate for patient in current state
RN must assess patient for particular med & evaluate if its been given for right reasons
if no reason is apparent, contact prescriber
